What Make&Model is your switch?
Are you certain it is capable of 1000Base-T? Many are not.
Does the Erthernet cable you are using have all eight wires and all eight contacts at each end? If it has only four or six (as many do) it is not useable for Gigabit Ethernet.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

Thanks for the info, the cable has 4 twisted pairs. I have used a short pre made cable as a test and that is showing green on the switch so I presume its a cable/conecter issue.

Once you have it stable, you can save a little startup time by configuring:
System preferences > Network > Ethernet > ( Advanced ) > Ethernet > Configure: Manually ...
... and set the speed to 1000BaseT and Full Duplex, flow control, and Jumbo Frames
This saves you the time to Auto-speed each time and gets you Full Duplex and Jumbo Frames even if your equipment would rather run slower or Half-Duplex, or smaller frames.
The only down side is that if your Router cannot connect the way you specify, it will not connect. But that can be addressed the first time you do this.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers
